FULLER Ton BATTERY TERMINALS.

Application filed December 22, 1926. Serial No. 156,394.

This invention relates to a device for pulling the terminals from battery posts, one of the objects being to provide a simple, compact and inexpensive tool of this character which can be used without pressing on the battery and injuring it. Frequently the posts become corroded so that it is practically impossible to loosen the bolt holding the collar upon the posts. The terminals have sometimes been removed by heating them with a torch but this frequently injures the battery.

An object of the present device is to provide a tool which can be quickly applied to the terminal, readily actuated to provide sufficient force to withdraw the terminal from the post, there being no danger of m urlng the battery in any way during this operation.

WVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a front elevation of the terminal puller in position.

Figure 2 is a side elevation thereof. 7

Figure 3 is a central vertical section through the puller, the screw and its nut being shown in elevation and the terminal being also shown in elevation, I

Figure 4 is a view'partly in plan and partly in section of the device.

at 4 so that the body cannot lift relative to the nut nor the nut drop out of position. Longitudinal displacement of the nut is prevented by striking the metal inwardly adjacent opposed faces of the nut as shown at extends through the nut 3 and has an angularhead 11 at its outer end whereby it can be turned readily with a wrench.

In using the device the body 1 is placed above the post A and the hooks 9 are swung toward each other so as to engage under the opposed 'ears E extending from the collar B. Screw 10 is then fed against the end of the post and by applying sufficient force to the-head thereof with the use of a wrench, the body 1 can be caused to pull away from the post, dragging with it the collar B. Thus the collar with the terminal wire extending therefrom can be disconnected from the post'A without subjecting the battery to pressure and without requiring the use of a heating torch or other means likely to injure the battery.

Importance is attached to the particular way in which the nut is assembled with the body 1 inasmuch as this enables the structure to be made very cheaply and at the same time prevents the parts from'becoming separated and lost when not in use.

What is claimed is: a

1. A terminal puller'for batteries including a longitudinally channeled body, tongues pivotally connected to the end portions of the body and having terminal hooks, a nut Referring to the figures by characters of firmly seated within the channeled body, there being inwardly offset portions formed by the Walls of the body. for holding the nut against movement relative to the body,

and a pressure screw extending through the 1 nut and body.

2. A terminal puller including a longitudinally channeled body, pivot devices exthereof, tongues mounted toswing on the tending transversely of the end portions pivot devices and having hooks at their free ends, a nut seated within the middle portion of the body, the sides of the body being ofi'set inwardly to hold the nut against 5 displacement in one direction, there being inwardly ofiset portions of the sides of the body adjacent the nut for holding said nut against longitudinal displacement relative to the body, and a pressure screw extending through the nut and body.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature; v

HENRY J. NOACK.
